Mary Catherine Williams was 31 when she vanished from New York City’s edges in the fall of 1992. She was last traced in Queens and was seen getting into a car with Joel David Rifkin on October 2, 1992; that encounter ended in violence and her life was taken that night. Her remains were discovered on December 21, 1992, in Yorktown, New York, and she was identified by dental records on July 6, 1993.

Police later reported finding one of her credit cards in the home Rifkin shared with his mother and sister, a detail that linked him to her death. Rifkin’s arrest on June 28, 1993, followed a traffic stop that led troopers to a woman’s body hidden in the back of his pickup; that custody produced confessions and recoveries that connected multiple victims to him. Williams’ death became part of the broader accounting of those crimes and her name was restored to the record after months of anonymity.

Did anyone who knew Mary Catherine Williams in New York in 1992 see her or remember her plans that autumn?
